Definitions

  • the invention relates to a transverse seam sealing device a tubular bag machine for the production of Tubular bag packs according to the preamble of claim 1 (see WO-A-86 04 559).
  • Such known tubular bag machines is from a Packaging material web first continuously formed a tube, each advanced by one bag length in his closed end section each a quantity of product introduced, and this end portion through a transverse seam sectioned on the bag package just completed a head seam and one at the new hose end section Bottom seam forms. Through a cut between the head seam and the bottom seam is cut off the finished bag package.
  • the hose is supported by two pairs of jaws, the one above and attack below the transverse seam, each in one upper position, advanced to a bag length and then released.
  • the cross seam sealing device then returns to start a new work cycle in the upper position back.
  • the sealing jaws of the transverse seam sealing device are in a space between the two pairs of jaws can be moved back and forth.
  • the sealing surface of the sealing jaws is interrupted by a groove in which a cutting knife for Cut off the finished sachet between the head seam the bag pack and the bottom seam of the Hose end section is inserted.
  • the cutting knife is firmly seated in one of the devices Sealing jaws, cuts through the tube already at Close the sealing jaws, and dip into a groove in the another sealing jaw.
  • the separating knife is in and in a groove of the sealing jaw retractable and has its own drive. It will be after advanced the sealing process so that it was the separation of the Cross seam.
  • the transverse seam sealing device according to the invention with the characteristic features of claim 1 has in contrast the advantage that on the one hand product particles in Cross seam area of the hose are tied, and that on the other hand the release agent has a temperature at which a Burning of product particles on the cutting knife is not possible is. This results in the operation of the facility considerable advantage that the very long service life of Separation device can be achieved.
  • Cross seam sealing device 11 arranged below the molding tube 10 of a molding device.
  • This Cross seam sealing device 11 is preferably to be preferred of the formed around the molded tube 10 from a packaging material web Hose 2 can be raised and lowered.
  • the cross seam sealing device is not shown in detail 11 arranged on a carrier, one by one Bag length is moved up and down.
  • the Cross seam sealing device also be stationary if the Hose, as also known per se, from one Hose feed device is transported.
  • the transverse seam sealing device 11 has two pairs of jaws 12, 13 and 14, 15, which are separated by a space 16 are spaced one above the other.
  • the jaws 12, 14 or 13, 15 are on each side of the tube 2 in their ends attached to cheeks 18, 19, which on horizontal Guide rods 21 of a not shown, per se known linear actuator against each other for clamping the Hose 2 are slidable.
  • Side walls of the jaws 12, 13; 14, 15 are to the To increase friction, elastic clamping pieces, for example Strands 23, 24, 25 and 26, 27 preferably made of rubber used when compressing the pairs of jaws 12, 13; 14, 15 flatten the intermediate hose 2 and hold on, being between the top Pair of jaws 12, 13 and the lower pair of jaws 14, 15 the intermediate hose section 3 is clamped flat is.
  • a separating knife 35 is also in the intermediate space 16 feasible, the tense at his advance Hose section 3 after making a transverse seam the sealing jaws 31, 32 transverse to the hose direction severed, the transverse seam lengthwise into a Bottom seam 5 at the hose end section 4 and into a head seam 6 is divided into the finished bag package 1.
